i don't see a problem with the following signal flow (indentation
represents the message stack):

symbol x, execute outlet 1
	t a b, execute outlet 2
		s kill-symbol-x, mark 'symbol x' deletable
	t a b, execute outlet 1
		s y, send
			r y, receive
				symbol x, set object
symbol x, returning from outlet 1, as it's marked as deletable, remove
it from the interpreter

Most of the trouble in this world has been caused by folks who can't
mind their own business, because they have no business of their own to
mind, any more than a smallpox virus has.
